Q1: Are there any issues with the glass, such as steam buildup or fogginess?
A: Typically, we use 5mm+12A+5mm double glass. Rest assured, our double glass is professionally crafted, ensuring no steam buildup or fogginess between the double glass.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all the doors and windows include frames, and installing them on walls is perfectly fine.
Q3: If the glass breaks without any apparent reason, should I be concerned about the rest breaking?'m afraid the rest will be broken
The glass would only break due to an impact force; it won't break on its own.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is advisable to use 5mm double glass because
sliding doors look unappealing with single glass. The wide space for glass would require excessive silicon filling if single glass is used.
5mm double glass is safer than 6mm single glass.
5mm double glass offers better soundproofing than single glass.
Q5: Can you use rubber instead of glass silicon?
A: Yes, but it can only be used on one side. The other side must use glass silicon, as double rubber is not strong enough and is more prone to falling off.
